How to Select a Transformer

Before going to the discussion on how to select a transformer, let us cover first some of the transformer basic fundamentals. Transformer is could be a low frequency like those used in 50Hz or 60Hz line. Transformer is could be a high frequency one like those used in switching mode power supplies. Transformer will transfer power from the primary to
